Optimal is very subjective lor. It's not optimal to use CZ lenses for Canon SLR as well (via CY mount adapter), but lots of people are happily using them anyway.
Alternative, don't worry about this optimal thing. You can still take good picture with the jupitar lens, and more importantly, you can learn about exposure using it too. Jupitar lenses are pretty sharp too, so no worries.

I was planning to buy a few more russian lenses with LTM actually, since they are so cheap. I guess cheap does come out dearer in the end eh?
